Abstract

The invention discloses a data management method based on rendering application data access characteristics. Different from a disk array storage mode used by the existing rendering application, the technical scheme adopts different storage designs for different data categories by summarizing the access data characteristics of the rendering application. Under the situation that the rendering application is enabled to operate normally, the memory of a rendering node is effectively used, and the data access time of the traditional rendering storage is reduced. Besides, data pre-access is taken into consideration aiming at the characteristics of frame data, and data required by rendering can be stored in almost all of the memory in the rendering operation process, so that the utilization rate of memory is improved. Meanwhile, the data management method is convenient to use as the design in the invention is flexible and feasible, the flexibility is embodied on memory allocation, and the available memory space is allocated for each node according to the size of a scene file; the feasibility is embodied in the aspect that the technical scheme in the invention is still available when the number of nodes is increased or reduced in the distributed environment.

Description

technical field [0001] The invention belongs to the technical field of high-performance computing, and more specifically relates to a data management method based on data access characteristics of rendering applications. Background technique [0002] Rendering is a key link in animation and film and television production. It takes about 30% of the entire production cycle and is a data-intensive and computing-intensive task. The current data management of the rendering cluster is to store the data required for rendering on the remote disk. When the rendering application needs it, it is read from the remote disk to the computing node. This data reading method makes the local rendering application wait , when rendering adjacent frames, frequent reading of lens data will be involved, then data contention will occur at the data access node, and the delay time will be longer. At the same time, the rendering application calculation will occupy a large amount of memory, and the memo...
